What Are Medical Devices?
Medical devices include any instrument, machine, implant, software, or tool used to:
- Diagnose medical conditions
- Monitor health status
- Prevent disease
- Treat illness or injury
- Support rehabilitation
They range from simple tools like thermometers to highly complex robotic surgical systems.
Medical devices are used in:
- Hospitals
- Clinics
- Laboratories
- Home healthcare
- Emergency services
They are critical at every stage of patient care.
A Real-World Story: When a Device Makes the Difference
A middle-aged patient diagnosed with severe heart blockage was at high risk of cardiac arrest. Instead of undergoing open-heart surgery, doctors implanted a coronary stent — a small mesh device that restored blood flow immediately.
Within days, the patient returned home, resuming daily life.
This example shows how modern medical devices reduce risk, speed recovery, and improve survival rates.
Major Categories of Medical Devices
